RESOLVED my secondary air monitor by switching out the check valves, mine were clogged but they didn’t have any back flow or moisture in the hoses so tech thought they were good I ended up getting them off (they were seized took a few different attempts with break free lube) I was trying not to break down tube. You need a 1” and a 7/8” Wrench, gotta get a good position on them to get opposing torque without twisting or turning. If your pump is good and make sure your small vacuumed lines are good too it’s worth pulling your check valves off and making sure they’re clear! New ones are $24 on Amazon or parts geek! Good luck! If you’re having this issue and have 100k plus miles it’s worth pulling them off and checking there’s bound to be buildup after tha many miles! You should be able to blow through them.
